CARRIERQOPERATING MECHANISM FOR BINDER-s.

Application filed January 29,1921. -Seria1No.'441,036

-' an attachment for binders whereby the bundle carrier device of thebinder may be operated automatically from power furnished by the binder.

Still another object is to provide suitable mechanism for causing thebundle carrier device to be tripped or swung to'discharging position,and returned to normal position; the mechanism being driven from amoving part of the binder.

Still another object is to provide means for holding the bundle carrieroperating mechanism inoperative during the time the bundle carrierishaving bundlesdischarged from the conveyor thereon.

Still another object is to provide acontrolling device adapted to becontrolled from a distant point from the operating mechanism forthrowing the bundle carrier operating mechanism into operative positionfor, swinging the bundle carrier to discharg ing position'and backagain.

Still a further object is to provide such a bundle carrier operatingmechanism that after a complete operation of the bundle carrier theparts will automatically be thrown out of engagement and held in thatposition until the controlling device is again actuated. I

Still a further object is to provide suitable means for varying theposition of the bundle carrier operating mechanism relative to thebundle carrier so that the movement of the bundle carrier may be variedas clesired.

Still a further object is to provide yieldmg means forthrowing thecarrier operating mechanism into engagement with a device driven fromthe binder so that the carrier operating mechanism may be operated formoving the 'bundle "carrier the parts 'beingso arranged that when thecontrolling device is operated the holding 111631131916- leased and thentheyielding means throws the carrier operating mechanism. intoengagement and operative position.

Still another-object is to provide a carrier operating mechanism adaptedto be operated from a moving part of a binder, the operating mechanismbeing suitably'mounted on the seat beam or pipe of the bindersjo (as notto interfere with the ordinary conveyor mechanism of the-binder.The-car: rier operating mechanism is so provided that its operation maybe controlled from a point distant fromthe o1j"dina'ry"carri er trippingmechanism which is ordinarily provided ona binder.

Still another object is to nrovide'suchan attachment for operating thebundle carrier by power, theattachment 'being'so *de-f signed that itwill operate in connection with the ordinary control or trip 'device'ofthe bundle carrier.

Still another object is to provide means for operating the bundlecarrier of abinde'r by power supplied from a moving-part of the binder;the operating mechanism being so provided that after a complete cycle ofoperation of the bundle carrier has been performed the operating"mechanism will then be automatically disengageda'nd at the same timewill be held out 'of'engag'e'ment until a -manually operable controldevice is again operated. 1

With these and other objects in view my invention consists in theconstruction, arrangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in which:

Figure 1 is a diagrammatic, perspective View of my carrier "operatingmechanism attached to a hinder, the bundle carrier and control device"being shown in connection that shown in Figure 2 and showing the waypower is applied from the binder.

Figure 5 is a rear end view of my device.

Figure 6 is a de ail sectional view taken through the holding device forholding the parts inoperative.

Figure 7 is an enlarged detail sectional view taken on the line 7-7 ofFigure 6.

Figure 8 is a detail sectional view showing how the power from thebinder is reversed.

Figure 9 is a side elevation of my device similar to Figure 2 showing amodified form of driving the device and for controlling the device.

Figure 10 is a rear view of my device as shown in Figure 9; and

Figure 11 is an enlarged, detail view taken on the line 1111 of Figure9.

In the accompanying drawings I have used the reference numeral 10 toindicate the frame of a binder to which is secured an auxiliary frame 11which supports the bundle carrier 12. The auxiliary frame 11 is providedwith braces 13 which are secured to toe binder supporting frame 14.

The parts just described are of the ordinary type found upon practicallyall makes .of binders.

The bundle carrier 12 is composed of fingers 15 which have their innerends fixed to a swinging bar 16. The swinging of the bar 16 causes thefingers to be moved to discharging position and return to their normalposition.

Fixed to the binder frame 10 is a seat pipe or beam 17 which is providedwith a suitable bearing 18. The grain when out passes upon a conveyor 19which delivers the grain after it has been bound into. a bundle by thebinder mechanism (not shown) onto the bundle carrier 12.

A. bearing 20 is fixed to the frame 11 and substantially in alignmentwith the bear g 18. .4 5. bundle carrier rocking shaft s journalled inthe bearings 18 and 20 and as one of its ends bent substantially at Ightangles so as to form an arm 22.

Fixed to the rocking shaft 21 adjacent to the bearing 18 is an arm 23.An ordinary foot t-rip device 24 is mounted on a supporting bar 32 andiscapable of swinging movement.

The foot trip 2/4 is provided with a crank portion 25. The lower end ofthe foot trip device and the arm 23 are connected together by means of aconnecting rod or link 26. i

v The swinging bar 16 of the carrier 12 is connected to the arm 22 ofthe rocking shaft 21 by means ofa link 27.

From the construction of the parts just described it will be seen thatthe moving of the foot trip device in the direction indicated by thearrow 28 will, cause the connecting rod 26 to move in the direction ofthe arrow 29 which in turn will cause link to move in the directionindicated by the arrow 30.

The bundle carrier 12 will then. move i the direction indicated by thearrow 3 which is the normal movement; that is rearward and downwardmovement of the bundle carrier so that any bundles of grain upon thecarrier will he slid ofi onto the ground.

My device is adapted to operate in con nection with the bundle carrierand the control rods for operating the same, My device consists of abeam or supporting bar which rests upon the seat pipe or beam 1? and isheld thereon by means of a two-part hearing or gripping device 33.

One of the parts of the bearing is fixed to the beam or support 82 whilethe other part extends part way around the seat beam 17. The two partsof the bearing 38 are held together by bolts 34.

The entire mechanism of my device which operates the bundle carrier ismounted upon the beam 32.

Substantially near the rear end of the beam 32 1 provide a'casting whichis provided with a pair of bearings36 and S7. A stub shaft 38 isprovided in the bearing 36.

A sprocket wheel 39 and a gear 40 are loosely mounted on the shaft 38.The sprocket and gear 40 are held together by means of bolts 41.

In order to drive the gear 40 from a moving part of the binder I mount asprocket 42 on the conveyor shaft 43. A chain 44 connects the sprocket42 with the sprocket 39 for driving the latter.

casting 45 is fixed to the beam 82 and is prowided with hearing portions46 and 47. The bearing portion 46 is in alignment with the bearing 37 ofthe casting and a shaft 46 is iournalled in the bearings 37 and 46.

The rear end of the shaft 48 extends be yond the bearing 37 and hasfixed thereto gear 49 in mesh with the gear 40.

From the construction of the parts just described it will be seen thatthe shaft isdriven in the opposite direction from the conveyor shaft 43.The reverse of the direction of the shaft 48 is caused by the use of thestub shaft 38 and the gear 40. The conveyor shaft travels in thedirection indicated by the arrow 50 while the shaft 46 travels in thedirection indicated b the arrow 51.

Rotatably mounted in the healing 4'? is a shaft 52 to which is fixed anincomplete crown gear 53. The crown gear 53 is pro-- vided with a flator incomplete portion 54. The incomplete portion 54 has no teeththereon, as is illustrated in Figure 3 of the drawings.

The gear 53 is provided with a web or disc portion which is providedwith slots 56,

the purpose of the slots 56-.being hereafter more fully-set forth.

The shaft 48 is provided with a gear '5? which is designedto mesh withthe crown gear 53.. and .whiclnnormally rests against theincompleteportion be of the gear as shown in Figure 3 ofthe drawings.

hen the teeth of the crown gear 53 mesh with thegear'? then the crowngear 53 is rotated.

mesh with the crown gear that the rotation of the crown gear 53 willcause the movement of the pit-man.

The movement of the pitman 58 causes the arm24c to be=swung upon itscrank portion l25,-which in turn causes-the rearwardniovei ment of theshort arm 23 on the rocking shaft 21 t this operation. imparts.niovement to. the bundle carrier 12.

The parts .are so arranged that when the bundle carrier 12 is in itsnormal .position thegear -57 rotatesadjacent to.the.incomplete portion545 ofv tl1e,gear53.

It will be understood that-it-is-necessary to provide some means forfirstmovingthe gear'53 to position where it- 'willimesh with the gear57.

.In order to-.provid'e for suchmovement-I employ a spring 61 which is-wonnd around the bolt 60 and has one end e'ngagedovith thepitman-58-and the other end with the arm The spring 61.normally:tends tomove the gear 53 to theposition shownin dotted lines in i-Figure 2 ofthe:drawings.

Itis-not desirable'to causethebundle oarrier to operate at regularspaced; intervalsfs'o it is necessary to ,provide some anea-ns forpreventing: the-spring 61 from causing the gears? 53. and $57- to: mesh.

In order to holdthegearo outofenggagement with'thegear 57Iprovide-a-pivOted pawl 62'pivoted on the:bolt 63.

The pawl6-2-is composed ofa pair ofsimilar spaced-members which areslightly spaced apart, and-are provided with a filler block 64 neartheir upper ends.

:The pawl 62 is ;pivoted in-a frame 65 which is composed of a pair ofsimilar shaped members having'a spacer66 placed therebetweeninear theirupper ends. and-a screw 67 is extended through the ,frame'65 andithespacer 6 6, and received into-a portion of the casting 35.

The frame 65 is also fixed tothecasting 35by means of a small bolt 68.

I The-twmme'mber's-of. the pawl 6293.1B5P10- vided with openings whichreceive a short Figure 2 of the drawings.

The rear end of the arm 71 has fastened thereto aspi ing-72 which isfixed to a lug 73 on the frame 65. The spring 7 2normal- ;ly' holds theupper end of the pawl 62 in its forward position.

A lug'fi tis-formed on the :pawl 62 on one side of the frame 65 and isdesigned to engage the frame 65 for limiting theamount of forwardmovement of the pawl-62.

Asimilar lug 75 is'fo'rmed on the pawl 62 on the opposite-side from thelug 74. The h1g7 5 limits the amount of rearwardmovement of the ,pawl62.

Fixed-to thedisc 55of thegear-53 is -a lockingzor-engaging member 7 6.One end of the engaging member 7 6 projects o'ut beyond thejperi'pheryofthe disc- 55. The en- ;gagingmember 7 6 isi'in alignment with the spacebetween the t'woqnembers of thepawl VVhenthe disc 55 isirotated theengaging -membe'r.76'first'strikes'the roller 70; as the disccontinuesto rotate thepawl- 62 is'mo'ved rearward against theaction ofthe spring 72 runtil the engaging memberstrikes against the filler block64.

When in th-is position the :pawl 62 locks the gear 53 against: anyfurther movement.

--V\. hen inthisiposition theggearw57 rests adj acent to the incompleteportion of-the gear "53.

EThe pawl 62=counteracts the normal movet nientaofthe. spring 61'whichwould normally ten d to throw the ge-ar '53 into engagement-with' the:gear 57. i

It will be seen that I have "provided holding device for automaticallyengaging the tmember 76 "for preventing any further movement oroperation of the mechanism which operates the bundle carrier.

FlXBd'fiO'tlTe forward end of the beam 32 and extending .upwarldlytherefrom is an angle iron frame 77 which'has pivoted: there to atritsupper end a'=disc 78. The disc. 78 isiprovided with aznotch79 initsedge, as illustrated in Figure 2 of the drawings.

"Oneside of the angle iron frame 77 ex tends part way into the notch? 9so that the pivotal "movement of the disc 7 8 in either direction 'willbe 'limited.

-Aibrace-80has one end fixed to the-angle ironiframe 'li' and its otherend-totheseat support 81 of the binder.

A bell crank lever 82 isipivoted at 83 on the-beam 32, onevendbfathebell crank lever 82 being connected to one end of the arm 71 by means ofa link or rod 84. The opposite end of the bell crank lever 82 has rod 85pivoted thereto and extends upwardly adjacent to one side of the angleiron frame 77 and has its upper end pivotally fixed in the disc 78.

A rod 86 is pivoted in the disc 78 and extends forwardly therefrom.

The parts just described are what may be termed the controlling device,which controls the operating mechanism for the bundle carrier.

The rod 86 may extend forward to a distant point or may have a wire orrope fixed thereto so that the disc 7 8 may be slightly turned or movedon its pivot from the drivers seat of a tractor.

The pulling of the rod 86 forward will cause the bell crank lever to beswung on its pivot which will move the rod or link 84 in the directionindicated by the arrow 87.

The arm 71 will then be swung on its pivot 63 to a position which willcause the pawl 62 to disengage the member 76 on the disc 55.

As soon as the member 76 has been freed from the locking pawl 62 thespring 61 will cause the gear 53 to be moved to position where it willengage the gear 57.

hen the gears 53 and 57 are in engagement the power from the binder willcause the tripping mechanism to operate the bundle carrier to move it toposition where the bundles" will be discharged therefrom, and thenreturned.

The engaging member 76 and the locking pawl 62 will engage as soon asone complete cycle of operation of the bundle carrier has beenperformed.

The operating mechanism then remains inoperative until the operatoragain pulls the rod 86 which causes the pawl 62 to disengage from themember 76 and again permits one complete cycle of operation of thebundle carrier.

The slots 56 are provided so that the pitman may be adjusted relative tothe position of the various parts of the device.

When the pitman is adjusted it causes the normal position of the bundlecarrier and the controlling rods 21 and 27 to be slightly changed sothat with each operation of the carrier operating mechanism the carrierwill be moved to discharging position and returned. 3

The amount of movement of the carrier may be varied by changing theposition of the pitman 58 relative to the remainder of the parts of theoperating mechanism. It

will be understood that by shifting the position of the pitman, itwillcause the original or starting position of the bundle carrier to bechanged so that the actual amount of movement of the bundle carrier maybe varied. I

It will be seen that with my device the power from the binder is usedfor operating the bundle carrier and that I am able to control theoperation of the bundle carrier from a point distant from the binder.

I am able to operate my device from the tractor seat without the use ofanyone on the binder.

31y device furnishes a positive means for operating the bundle carrierand no effort on the part of the operator is necessary save for thetripping of the pawl 62., or the tripping of a foot release which may belo cated near the binder seat.

My device may be made as an attachment to be placed on the ordinarybinders, or may be originally installed when. the binder ismanufactured.

In Figures 9, 10 and 11 of my drawings l have shown a slightly modifiedform of driving mechanism and mechanism for controlling the operation ofmy device.

The conveyor shaft 43 as shown in Figure 9 is provided with a pulleywheel 88. he shaft 48 which is mounted in the bean ings 46 and 37 isprovided on its outer end with a pulley wheel 89 which is substantiallyin alignment with the pulley wheel 88.

A belt 91 of any suitable material is placed over the pulley wheels 88and 89 and is crossed so as to operate the shaft 48 in the directionindicated by the arrow 51.

,Vhen the shaft 48 is driven direct from a pulley it is not necessary touse the stub shaft 38 or the gear 40. I have found that by using a beltI can drive the shaft 48 direct, since a belt can be crossed to anydesired direction.

It will also be understood that when a chain is used for driving mydevice it may be connected to some moving part of the binder which istravelling in the proper direction and it will then not be necessary touse the intermediate gear 40 for reversin the direction.

There are a great many makes of binders and it is necessary to providefor some slight change so as to properly install my attachment to thevarious makes of binders.

The bracket 35 as shown in Figure 11 is provided with only one bearingwhich is 37 in which is mounted the shaft 48.

In this form of device the control mechanism which operates the pawldevice is carried below the seat beam and extended forwardly to aposition adjacent to the drivers seat of a tractor.

WVhen the control device is carried below the seat beam a link 92 issecured to the forward end of the arm 71 instead of the link 84. A lever93 which lies in a hori zontal plane is suitably supported from thebinder frame.

The forward end of the link 92 is secured to the lever 93; A cord 94 isfastened to CJI til

the opposite end of the lever 93 and extends forwardly to the driversseat of the tractor whereby the cord may be drawn for tripping the pawlwhich operates my device.

By the use of the lever 93 I am able to lead the cord forwardly so thatit will not interfere wit-h the cutting mechanism of the binder or thetravel of the grain which has been cut.

The cord will pass free of the reel of the binder and will not beinterfered with by any of the mechanism of the binder.

It will be seen that by this method of driving my device I haveeliminated the use of expensive gears and have to a certain extenteliminated part of the bearings and yet have provided a very simple andefficient device.

It will be further understood that I have shown two different forms ofmechanism for driving the device, but it is understood that I intend tocover by my claims various methods which may be used in driving thedevice which may be reasonably included within the scope of my claims.

It will be further understood that slight changes will have to be madefor adjusting and regulating the positioning of my device on a binder sothat it will operate efiectively on various makes of binders.

Some changes may be made in the construction and arrangement of theparts of my machine without departing from the real spirit and purposeof my invention, and

it is my intention to cover by my claims, any

modified forms of structure or use of mechanical equivalents, which maybe reasonably included within their scope.

I claim as my invention:

The combination of a binder having a bundle carrier capable of movingfrom carrying to discharging position and back, with a carrier operatingmechanism arranged to be operated from a moving part of the binder,means for moving said carrier operating mechanism to position for suchoperation, and means for varying the position of the carrier operatingmechanism relative to the bundle carrier whereby the amount of movementof the bundle carrier may be varied.
